TENSION DEVICE FOR MACHINES FOR MAKING CHENILLE R ORNAMENTAL CORD.

SPECIFICATION forming part of Letters Patent No. 461,059, dated October 13, 1891.

Application filed April 8, 1891- Serial No. 338,162. (No model.)

To aZZ whom it may concern: ley D, down around the lower part of the Be it known that I, ALWILL URBAHN, a drum A again, between the drums A and B, resident of the city of Brooklyn, county of up to anrl'around one of the smaller grooves Kings, and State of New York, have invented in the drum D,again down to the drum A, up 5 a new and useful Improvement in Tension bet-ween the drums A and B, then preferably Devices for Machines for Making Chenille or under an extension of the pivot e, up over the OrnamentalOord, of which the following is a larger groove in the pulley D, and down into full, clear, and exact description. the proper receiver. It is very desirable that My invention relates to the improvement there may be a suitable tension on the cord 60 [o in machines of the class described in my patas it passes over the largest groove in the out, No. 206,928, of October 31, 1882, and in pulley D from the drum A. Therefore a ring I my patent, No. 293,605, of February 12, 188i. of a circumference greater than the largest The object of this invention is to perfect circumference of the pulley D is supported the mechanism by which the ornamental cord by the pulley D in the groove of the largest 65 I 5 is discharged from the machine and by which circumference, so that it will cause the cord,

a proper tension may be kept on the finished as it last passes over the pulley D, to be to a cord during the process of making the same. certain degree fractionally held between said The invention consists in the new combi' ring I and the largest groove in said pulley nation of parts hereinafter described and I). A toothed wheel J is connected with the 70 2o claimed. drum A, which turns loosely on the shaft a. Reference is had to the accompanying Fixed to the shaft a is a toothed pinion g, drawings forming a part of this specification, which meshes with the teeth of a larger geari wheel h. This gear-wheel h is hung on the Figure 1 is a face view of my improved maspindle e and carriesapinion i, which meshes 75 2 5 chine. Fig. 2 is a part side elevation of the into the wheel J. The shaft a is revolved by same. Fig. 3 is a plan view of Fig. 2. the drum K, which is turned by a moving A is a drum turning on the shaft (1, which belt L, and the system of cog-wheels prehas ts bearing in the supporting frameviously explained is set in motion thereby. work Q Because of the arrangement of these wheelsa 8o B is another drum bearing against the peslow rotation is transmitted to the drum A,

This ley H, to take the course previously described lever is pivoted to the frame-work O at e. At and finally pass from the grooved pulley D the upper end of the lever E is riveted or to the receiver. The tension of the cord M 85 otherwise formed an arm F. A grooved pulbetween the drum A and the smaller grooves ley D turns on an arbor d that projects from in the pulley D causes the pulley D to turn. the arm F. One of the grooves, of which By providing a machine of the kind herein there maybe several, in this pulleyI) is prefdescribed with this improvement I am enerably of larger circumferencethantheothers. abled to give to the cord M the proper even 0 A spring G, fastened at one end to the frame tension, and also prevent any chance of the O and at the other end to the arm 1?, causes cord M becomingjammed between the drums, the drum B to bear against the drum A to a thereby becoming spoiled for a distance. By degree determined by the strength of the experiment I have demonstrated that with Spring. G. this improvement the daily capacity of the 5 H i pulley hung in the upper part of the machine is greater than it would be without frame 0' said improvement. The necessity of care on In my improved machine the cord M is the part of an attendant is largely decreased brought from the pulley I-I down around the and the evenness and the quality of the cord lower part of the drum A, up between the M is greatly improved. 5

drums A and B, up to and around the upper Having thus described my invention, what part of one of the smaller grooves in the pul- I claim 1s- 1. The combination of the grooved pulley D and its fixed bearings with the lever E, carrying the drum B, and with the drum A, hung in fixed bearings, and means for revolving the same, all for allowing the cord to be placed in several layers around the pulley D and drum A, substantially as shown and described.

2. The combination of the pulley D, having two or more grooves, one of which grooves has a larger, circumference than the other, with the cylindrical drum A and means for rotating said drum,-and with means,substantially as described, for feeding a continuous cord first to the circumference of the drum A, then to one of the grooves of the pulley D, thence back to the drum A, and finally to another groove of a larger diameter than the first of the pulley D, and thence to a suitable receiver to produce differential tension in the said cord, substantially as herein shown and described.

3. The grooved pulley D, carrying the loose ring I, in combination with the drum A and means, substantially as described, for rotating the same, all for the purposes herein shown and described.

4. The grooved pulley D,carrying the loose ring I, in combination with the drum A and the spindle c, with means for revolving the drum A, said spindle e serving as a tension device for cord passing from the pulley D to the drum A, all substantially as and for the purpose specified.

5. The combination of the frame 0, drum Ayhung therein, and means for revolving the same, with the lever E, pivoted to the said frame, grooved drum D, hung in said frame, drum B on lever E, and pulley H, hung on frame 0, all arranged substantially as herein 40 shown and described.
